SPECIFICATION forming part of Letters Patent No. 735,737, dated August11, 1903.

Application filed December 11,1902. Serial No. 134,855. (No model) ToaZZ whom, it In/coy concern;

Be it known that I, OARL'EDUARD FLEM- MING, manufacturer, residing at164 Hauptstrasse, Schonheide, Erzgebirge, Germany, haveinVe-nted'certain new. and useful Improvements in Machines for DrillingandFilling Brush-Backs, (for which I have applied for a patent inGermany, datedSeptember 15, 1902,) of which the following is aspecification.

In the machine for drilling and filling brush-backs described in thespecification to United States application, Serial No. 74,231, filedSeptember 3, 1901, the movable frame of the automatically-operatingmachine with horizontally-placed tools carries all the mechanismrequisite for the shifting of the slides carrying the brush-backsinclusive of the templet-disk, so that only the movement of thetemplet-disk and that of the frame have to be effected from the fixedframing. With this arrangement of the machine irregularities may occurin the working, because the ratchet pawl after the movement of the framedoes not again engage with one of the teeth-spaces of the templet-diskin particular when small brushes are to be made, and consequently thedistanee'between the teeth of the templet-disk is very small. Accordingto the present invention the said irregularities are obviated by alsomounting the ratchet mechanism upon the movable frame, so that theratchet-pawl remains in gear with the templet-disk while the frame isbeing moved. By this arrangement also the ratchet mechanism is renderedmore simple of con-'- struction.

On the accompanying drawings the improved arrangement ofthe ratchetmechanism is shown applied, by way of example, to I a machine having aframe with rectilinear to-and-fro movement. V I

Figure 1 shows a side view, and Fig. 2 shows a part perspective View,ofthe upper part of a machine; and Fig. 3 is a side elevation, and Fig.4 is a top plan view, of a complete machine embodying this invention.

As shown in Figs. 3 and 4, the camewheel 3 is turned by means of themain shaft 1, which is arranged in the rigid frame e of the machine andis driven, by pulley 2. The 1ever 4, which is pivoted at one end to theframe e, is reciprocated by means of this cam-wheel. At the other end ofthe lever 4 is a shaft 5, to the ends of which are attached two rods 6.The latter are pivotally conoted at 9 to the main frame and are providedwith slots 10, which engage pins 11 on a movable frame O. By turning theshaft 1 the frame O is caused to'reciprocate in guideways 12 in theframe e.

The ratchet mechanism is mainly the same as described in the said formerpatent, and the corresponding parts are marked with the same referenceletters and numerals. The movable frame 0 carries in the known mannerthe templet-disk 7, the step-by-step motion of which is effected by thepawl 2 1, spring 25, and 'doubleended lever 22. These parts are mountedon a support a, fixed to the frame 0. In this example of constructionthe two-ended lever 22 has connected to it a second twoended lever 1),whose pivot c is mounted on the frame 0, and whose hook-shaped end disin proximity to the fixed framing of the machine. On the fixed fra'minge, which serves as a guide to the moving frame 0, is fixed ablade-spring f. As soon as the frame 0 moves away from the machinethatis to say, to the right hand at Fig. 1,.the hooked end at of the lever19 bears against the fixed framing e, (the position shown at Fig. 1.) Onthe further the spring f, and thus the two-armed lever 22 is turned andthe pawl 24 raised. When the frame Omoves to the left hand, the curvedend 01 of lever 19 sinks again, and the pawl *24 consequently alsosinks. The spring 9 serves for insuring the said motion of lever b.

When the machine is required to make a larger ora smaller number ofholes in the brush-backs,. so that the pitch or the teeth of thetemplet-disk 7 requires'to be altered-, 'the ratchet motion. must bemade to take place correspondingly earlier or later. For this purposethe abutment-piece h on the framing e for the curved lever is madeadjustable in a guide 1'.

Having thus particularly described the ma nected with double levers 8,which are pivmotion to the right it'is raised, together with ture of mysaid invention and the best means I know of carrying the same intopractical effect, I claim- 1. In an automatic machine for drilling andfilling brush-backs with horizontally-placed tools, in which the movableframe carries all the mechanism for shifting the brush-backs, a fixedframe on which said movable frame is m0untcd,a ratchet device for thetemplet-disk mounted on the said movable frame and operated from thefixed frame, and means for holding said pawl in engagement with thetempletdisk during the movement of the movable frame.

2. In an automatic machine for drilling and filling brush-backs of thekind herein referred to, a fixed frame, a movable frame mounted on saidfixed frame, a templet-disk carried by said movable frame, a ratchetdevice for the templet-disk mounted on the movable frame which carriesthe mechanisms for shifting the brush-backs, a lever pivoted to saidmovable frame and operating said ratchet device, and an abutment-pieceon the fixed frame with which said lever comes in contacton the movementof said frame, substantially as and for the purpose described.

3. In an automatic machine for drilling and filling brush-backs of thekind herein referred to, a fixed frame, a movable frame mounted on saidfixed frame, a templet-disk carried by said movable frame, a ratchetdevice for the templet-disk mounted on the movable frame which carriesthe mechanisms for shifting the brush-backs, a lever pivoted to saidmovable frame and operating said ratchet device and an. adjustableabutment-piece on the fixed frame with which said lever comes in contacton the movement of said frame, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
